Silly as it is, one thing that has been holding me back on making further progress with free-the-mallocs.com is that I'm still trying to come up with a good logo design. The problem of course is that it is really hard to come up with a design that seems fitting. However, while typing this, I was just struck by using a design reminiscent of the various "free foo" and "save the bar" campaigns.
After spending a few minutes with Google seeing what other sites with a "free the" theme, I'd have to say that most of them weren't really very inspirational. I probably liked Free the Grapes the best, but I'm not sure what I would draw for a malloc in shackles.
